Synthesis Mica tape
Product description
The calcined mica tape uses high-quality calcined mica paper as the substrate, glass fiber cloth or carbon-free polymer film (such as PE) as a single-sided or double-sided reinforcing material, bonded with silicone resin, baked and dried at high TEMP

Catagory

According to different reinforcement materials, it can be divided into: 5461-CM-GS / FIRO-CM calcined mica single-sided glass fiber tape

Note: the meaning of product code

5461: Product serial number CM: Calcined Muscovite


Characteristics

◆ Excellent insulation performance at high temperature. 5461-CM calcined muscovite belt can guarantee no breakdown within 90 minutes under the temperature of 950 ~ 1050 ℃ and voltage of 600 ~ 1000V. ◆ Good environmental performance, the product composition does not contain asbestos, and no toxic gas will be generated under high temperature. ◆ It has the characteristics of acid and alkali resistance, anti-corona and anti-radiation. The finished product is dry, non-blocking, has good flexibility and flexibility, and has high tensile strength when wrapping wires and cables at high speed. A

Use common sense

The technical personnel should select the mica tape with appropriate width, wrapping tension, angle and wrapping speed according to the wire diameter. No tape breakage or packet leakage should occur, and the surface of the insulated core after wrapping should be smooth and flat without mica falling off.

When winding small cross-section wires, the mica tape is easy to fall off due to the small radius of curvature of the package. At the same time, the width of the mica tape is narrow and the tensile force is small. Therefore, the tension and speed of the package should be controlled uniformly to prevent the tape from breaking and falling. powder. The number of cladding and overlap ratio of mica tape vary depending on the material properties, specifications and model of the cable products, and need to be determined by the cable designer based on the fire resistance test results.

According to the IEC test standard for refractory cables, we recommend to wrap around 2 layers, the lap rate is not less than 50%, that is, the wire is wrapped by 4 layers of mica tape
